kinda stuck valve...

[XJkid]

I think drilling a hole in that hardened steel may prove to be next to impossible.

I'm hip! I was trying to make a removal tool using a drilled bucket(I think a CrazySteve idea) and I couldn't even get a brand new solid carbide bit to bite into it.

your picture close up, I see at the 2 o clock position of the offending bucket some scrapes or scratch marks.

they came after, from the screwdriver.

A really drastic measure to remove a stuck bucket if you can not get it any other way would be to remove all electrical connections from motor remove the TCI unit and use an electric welder and stick a rod to the bucket to get it out. I have not done this in a motorcycle but used it in a pump one time to remove a plunger that could not be drilled. It would really be safer to even remove your head to do this.


As stated this should be a last ditch effort to remove something when all drilling and other options have failed. If you can not get it out you may want to take the head to a machine shop and get them to do this. That way if there is a deep scratch they can make a recomendation on what they can do to fix the head it might not cost as much as you think and depending on how bad may not need anything but clear a burr and and or a new bucket.

got it out

well, i got the bucket out. i took it to a welder and he welded a t handle up, then welded it to the bucket, came right out. right away, i could see that the wear on the bucket was uneven and there were 2 decent scratches on the wall. so options as far as i see it are take the valve and springs etc out and polish those scratches out. or scrap the head and get another. i think im going to try and polish it. is there anything i can use to compress the springs or do i need to get the valve compression tool?

Buy the valve compressor or read through this, You already have the trashed bucket to make it work.

That McGyver tool of Tods will work if you have the head off but with the head on there you'll have to rethink it.

If you run the piston up to TDC in that cylinder it should hold the valve up far enough to remove/install the keepers. Don't let that piston go down or the valve will drop into the cylinder with the spring and keepers removed.

To push down the spring I think if you take a socket the right size and open up the side of it about 1/3 of the way around and use one of the cam studs as a fulcrum you could lever that spring down and pull the keepers out the hole in the side of the socket.

Clear as mud? It works perfectly in my minds eye.

As stated by the former members make a tool I just used an old 8 inch clamp and welded a 3/4 inch 2 inch long piece of pipe on the flat side of the clamp then drilled holes into the pipe I welded on there to create a hole to work with the keepers. You would not really have to weld it but it does make it easier to control. You should be able to just use a brake cylinder hone to clean up the cylinder and if it does not allow the bucket to wiggle back and forth you should be ok. Sorry it gave you so much trouble but you are better off fixing it now it could have in time caused much more damage. There are times that you might be better off just running things. This is one thing that seems simple but just gets worse the longer you leave it..

[BA80]

I'm sorry, did I miss something? Did you pull the head off?

[DGXSER]

I inherited a tool from a fellow member when he bought a real tool. It is basically a shirt length of PVC pipe with a cap on the end. with about a window cut ut about third the diameter and about an inch high to access the keepers. Put the PVC on the valve spring, use a large C-clamp to compress the valve spring and reach the keepers through the window.

[BA80]

That's what I was saying about the socket but I guess PVC would be strong enough huh?

[Shockman54]

@BA80, yes, i took the head off. i had an extra gasket, so i wasn't worried about that, and i needed it off to bring it to the welders shop. plus i want to clean the head totally and remove all the valves to make sure its totally clean before putting it back on... i think i'll try that socket idea, as it means i wont have to drill through that bucket. plus i kinda like the T handle welded to the bucket, its a good decoration for my garage.
where can i get those valve seals btw?

[BA80]

You might just check with your local bike shop since they are the same as some other bikes but here's some on ebay too.

If I were you, I would use after-market Viton valve stem seals. They cost slightly more but the material they're made of is supposed to be more durable and less likely to harden than the OEM ones. I've used them on several bikes. They're often green in colour.

[Shockman54]

ok, i used the socket idea to get the valves out, and the offending valve was bent. so theres the answer to all my questions as far as why it wasn't moving freely. my next question is, where can i get another exhaust valve for my 79? i looked on ebay, but didn't find any (other than ones that where in the head still, and i don't want to buy a whole head to get one valve...) anyone have one or know where i could get one? (i assume one from my 81 won't work...) and can i take the bottom (where the valve seal is and all that.) out of the valve guide?
the bent valve

the bad valve guide (going to refinish it with a brake hone.)

the socket i used to make the valve removal tool.

[natemoen]

I can look through my valves and see if I have a good exhaust and will let you know.
